  TAPiON - Polymorphic Deciphering Algorithm Generator Project
------------------------------------------------------------------------


SUMMARY



DETAILS

TAPiON engine was developed to avoid code detection (shellcode/whatever). 
The engine can create unique deciphering algorithm, encrypt the original 
data and decrypt it on the fly (while code executes).

Features:
 * Decryption key based on randomly generated deciphering algorithm 
(attacker breakpoint insertion will cause invalid decryption)
 * Decryption based on CPU time (selected randomly) - anti emulator code
 * RDTSC / coprocessor instructions usage - anti emulator code
 * Random step of block xoring
 * Random step of key increasing
 * Random registers usage
 * Multiple instructions variants
 * Block swapping
 * Garbage engine (normal instructions / coprocessor instructions)
 * Block swapping
 * Random deciphering algorithm size
 * Multiple deciphering algorithm layers generation
